Wellbore Stresses in Poroelastic Media: Should Biot's coefficient, alpha = 1.0 Yield the Same Results as the Expressions for Linearly Elastic Media?

Haimson and Fairhurst (1967) derived equations for the near-wellbore stresses (axial σyy, tangential σθθ, radial σrr...) around a pressurized hole in a porous, permeable "poroelastic" medium...
